Sourcegraph vs Mapnostics

Sourcegraph is built for fast code search across many repositories — find every call site, navigate definitions, grep at scale. Mapnostics is built to explain how one codebase fits together: the dependency graph, the hubs everything routes through, and what a change reaches.

Name-pattern match only, not a compliance assessment — verify each column before treating it as a finding.

Where regulated-shaped data is touched

customers.email4 files

Where the candidate columns above are actually read or written — not a claim about which regulations apply or whether they're satisfied.

Routes

URLs, methods and middleware coverage from the file tree

9 API routes · 15 pages

2 routes with no recognised auth evidence and no middleware coverage

3 of 9 API routes show rate-limiting evidence

Evidence only — a route with none may throttle through a helper this does not recognise, and this codebase declares no policy that every route must be rate-limited.

Performance patterns

Nested loops and sequential awaits — structural shape, not a speed claim

Structural shape only — not a claim either pattern is actually slow. Some sequential loops here are deliberate (rate-limited API calls).

Where Mapnostics is different

✓

The dependency graph, not a search box

Mapnostics maps every file, import and route as a live graph, highlights the hubs everything routes through, and layers ownership and schema over the same canvas.

Learn more →

✓

Why each file exists

The Intent Map explains the purpose of each file and the capabilities it implements, with an evidence block separating measured facts from inference.

Learn more →

✓

A ranked path into the code

Mapnostics generates a reading guide from your actual codebase — real entry points, real dependencies — so a new engineer knows where to start.

Learn more →

Where Sourcegraph is strong

Sourcegraph's multi-repo code search and navigation are mature and fast, and for a large organisation searching across hundreds of repositories that breadth is hard to match. Mapnostics goes deep on one repository at a time — its structure, its blast radius, its ownership — rather than wide across many. If your core need is “find this symbol everywhere”, Sourcegraph is built for it.
